For decades, wasting and stunting have been approached as separate conditions, largely disconnected in advocacy, programming, policy and financing. This has had negative implications for how children receive nutrition interventions and services across the world: support is often provided by different stakeholders who offer different interventions, often in different contexts, to different age groups and with different timeframes. A systematic review of evidence was published in 2021 in the journal Maternal and Child Nutrition. This technical brief outlines some of the key findings within the systematic review and provides an opportunity to consider the programmatic and policy implications.
